摘要
Abstract
As a geophysical exploration method,high precision magnetic measurement has many character-istics,such as easy to operation,non-destructive to the site,low cost and high efficiency.It is usually ap-plied in geological and mineral exploration.However,due to its susceptibility to site environmental inter-ference,it is less used in engineering investigation.In water conservancy,the detection of steel buried ob-jects in reservoir dams can be carried out with high precision magnetic surveying because the detection site is on the reservoir dam with fewer human interference sources.Through high precision magnetic measure-ment of existing steel buried objects,the detection effect of high precision magnetic measurement on steel buried objects in reservoir dam foundations has been studied.The collected high precision magnetic meas-urement data arehave been corrected,polarized and processed with first order derivatives.The magnetic a-nomaly characteristics have been analyzed to infer the planar position of the steel buried objects,and the burial depth of the steel buried objects has been determined by the tangent method and power spectrum method.It will provide a basis for subsequent dam reinforcement work.The detection results show that high precision magnetic measurement can effectively detect the position of steel buried objects.It can be used for the detection of steel buried objects in reservoir dam foundations.关键词
